Yes Virginia, there is a speed limit.

Sounds like someone figured it out but a power commander v won't eliminate the speed limiter. But an ecu re-flash from Guhl Motors will. And they can raise the rev limit of the engine.

I have read that one possibility for Honda's speed limit is that the stock bike just isn't designed to safely run that fast. I know mine felt a little wobbly at 110mph before I upgraded my tires and suspension.

I bought my CB because I liked the retro look but also because I wanted a bike I could easily customize but that had a modern engine.

Initially I thought my changes would be purely cosmetic but I realized there was a much more capable bike hiding in plain sight with some performance upgrades.

I've thoroughly enjoyed turning my CB into a sportier version of itself. That has included flashing the ecu, removing the speed limiter, and increasing the rev limit 500 rpm's. I have also replaced the exhaust and made some air intake changes. I had it tuned on a dyno and the difference is a lot of fun on something that doesn't look like it should go that fast. I have also switched to 17" wheels and dropped a tooth on the front sprocket.

It got up to 130mph on the dyno and 93hp. I have had it over 120mph and it felt much more stable than it did at 110 before the upgrades.

So even though I never bought the CB to ride like a sport bike I do now and I love it. I spent the weekend riding with a very experienced group of FJR riders in the mountains and the CB kept up to their amazement.

I love this bike.
